Timothy Stromberg, RLA, ASLA

Mr. Stromberg is the principal in charge of SGA’s design studio and is a landscape architect and urban designer with expertise in the design of urban environments, public spaces, and riverfronts. Over his professional career, Mr. Stromberg has specialized in dealing with highly disturbed and contaminated landscapes. The foundation of Mr. Stromberg's work is in brownfields revitalization, not just physically cleaning up their contamination but also repairing their potentially complex landscape systems and contextual relationships. Understanding a site’s natural, socio-economic, geo-political, historical, and built systems is vital to a project’s long term sustainable success. Mr. Stromberg, through the SGA's design studio, advocates engaging these complex systems to create site specific solutions that are innovative and constructible. The legacy of many industrial activities results in sites that have been disturbed to an extent that they can never be return to their former ecological state. Therefore, creating entirely new types of landscape conditions that still harness ecological processes has lead Mr. Stromberg to develop innovative methods of landscape programming. His approach interweaves existing site infrastructure and highly disturbed conditions with new site frameworks such as tapping latent natural processes, introducing hybrid plant communities, establishing modern infrastructure strategies, and creating new settings for social and economic interactions.

His recent project experience includes overseeing several U.S. Environmental Protection Agency Region 3 funded brownfields projects. He is overseeing a Riverfront Master Plan for Ronceverte, WV along the Greenbrier River that includes an estimated $100M proposed flood mitigation project to be implemented in partnership with the U.S. Army Corps of Engineers. Additional U.S. EPA funded projects include an industrial riverfront master plan for Nitro, WV along the Kanawha, River and an affordable housing project located on several brownfields sites in McDowell County, WV.

Mr. Stromberg is also developing riverfront park and water access concepts for a 12 mile stretch of the Ohio Riverfront near Pittsburgh, PA, including the 4 mile stretch of the former LTV Steel Aliquippa Works in Beaver County and an urban parks master plan for Lower Merion Township adjacent to the City of Philadelphia.

Serving as project landscape architect, Mr. Stromberg was part of a design team responsible for developing the West Newton Simeral Square Plaza, designed over a remediated gas station site adjacent to the Youghiogheny River. He developed construction documentation for the creation of the project’s new riverfront plaza, farmer’s market building and performance stage.

Prior to forming SGA, he worked at the firms of Oehme van Sweden & Associates (OVS) in Washington, D.C., Langan Engineering in Elmwood Park, NJ, and The Olin Partnership and Gannett Fleming, Inc. in Philadelphia. At OVS he was part of the firm’s design team responsible for developing the West Collections Master Plan for the Chicago Botanic Garden and conceptual and final design drawings and specification for a major new pedestrian bridge connecting the expansion to the current public areas of the garden. This project focused on a major expansion to the Chicago Botanic Garden and included the expansion of the plant collections, educational nodes, outdoor classrooms, and wildlife habitat. A key component of the project was the integration of the existing native prairie fire regime and a riparian swale with the proposed plant collections, allowing for the two to overlap uninterrupted. This approach created a "patchwork pattern", providing a continuously picturesque landscape with built-in fire boundaries allowing for burning maintenance of the fire regime landscape. In a related effort for the botanical garden, Mr. Stromberg also served as the project manager/lead project designer responsible for developing the selected bridge design for the Plant Evaluation Bridge extending over the lagoon between Evening Island and Lavin Evaluation garden.


Mr. Stromberg holds a Master of Landscape Architecture from the University of Pennsylvania and a Bachelor of Science in Ornamental Horticulture and Environmental Design from Delaware Valley College. He is member of the American Society of Landscape Architects.
